Skeletal System

What are the five types of bones in the human body?

• long bones, short bones, flat bones, irregular bones, and sesamoid bones

• red bones, blue bones, green bones, yellow bones, purple bones

• smooth bones, rough bones, shiny bones, bumpy bones, soft bones

• big bones, small bones, tiny bones, huge bones, gigantic bones

What are the functions of the skeletal system?

• Digestion, respiration, excretion

• Support, protection, movement, blood cell production, storage of minerals and endocrine regulation

• Vision, hearing, taste

• Reproduction, circulation, immunity

Describe the structure of a long bone.

• The structure of a long bone consists of a shaft (diaphysis) and two ends (epiphyses), with a hollow medullary cavity containing bone marrow.

• Long bones have a medullary cavity filled with muscle tissue instead of bone marrow

• Long bones are made up of only one end (epiphysis) and no shaft (diaphysis)

• The structure of a long bone consists of a single solid piece with no hollow cavity

Explain the process of bone remodeling.

• Bone remodeling is a result of muscle contractions.

• Bone remodeling is a passive process and does not involve any cells.

• Old bone is resorbed by osteoclasts and new bone is formed by osteoblasts.

• Old bone is formed by osteoclasts and new bone is resorbed by osteoblasts.

Which type of bone is responsible for protecting vital organs?

• Irregular bone

• Long bone

• Flat bone

• Sesamoid bone

How do bones support the body?

• By providing structural support and protection.

• By storing excess glucose

• By regulating body temperature

• By producing red and white blood cells

What is the function of red bone marrow?

• Produces red and white blood cells and platelets

• Regulates body temperature

• Produces digestive enzymes

• Stores fat cells

What is the role of osteoclasts in bone remodeling?

• Responsible for building new bone tissue

• Responsible for breaking down bone tissue

• Responsible for producing red blood cells

• Responsible for storing calcium in the bones

Name the three types of bone cells and their functions.

• Osteoblasts, osteocytes, and osteoclasts

• Bone marrow cells, cartilage cells, ligament cells

• Calcium cells, phosphorus cells, collagen cells

• Femur cells, tibia cells, fibula cells

How does the skeletal system contribute to mineral homeostasis?

• By storing and releasing minerals such as calcium and phosphorus as needed

• By transporting minerals to the digestive system for excretion

• By producing hormones that regulate mineral levels

• By converting minerals into energy for the body
